  1. Just as an aside, a brand new 400 engine is currently around 25,000euro from Ulrich Gerent. This is 300+ hp and 320+nm torque. Considering that a historic bda with 260hp and much less torque is £25,000 from the usual uk suppliers, that is very good value. He has brand new head castings and all brand new internals, and that is supplied dyno run, ready to bolt in and go.
  2. Little update, looking at exchange rates and various complications with existing engine parts, it's actually going to be cheaper to get a new engine built at Risse and sell the existing parts, so that's the new plan!
  3. Digging up this topic as I'm doing some "sorting out" regarding a few 400 rear axle related things. Just measuring up on a good straight 400 road car with no known accident history etc so I can make a jig for locating the rear chassis rail sections on the 'shell. This is now done and I have made a few observations, which largely agree with what's above but just thought I'd record them here for posterity and future reference! The upper link brackets appear to be as near as makes no difference 12 degrees outwards from perpendicular with the axle tube. The upper links are 296mm long between centres Lower links are 16 degrees inwards from perpendicular. Lower link brackets on axle are spaced further apart on 400 axle compared to commodore axle Upper link brackets are closer together on 400 than commodore Rear shock absorber mounts are higher up on lower link brackets on 400 compared to commodore. Panhard rod mounting is different between 400 and commodore
  4. Next question!......am I being stupid or can I use forged senator 24v pistons? Nobody used to list them but now I see that Wossner list them from stock, and up to 96.5mm bore........
  5. Right, well have got a set of the mercedes pistons that are touted as being the thing for the job and they don't look much good to me ! The comp height is taller (last thing you want on a big bore CIH!) and the gudgeon pin considerably bigger. I think Steve you are probably right!! Looks like custom forged ones! Could you tell me where you got yours from?
  6. Ditto all the above, it's strong enough if the a panels and inner wings etc are good
  7. Yes but the girdle and pickup pipe don't, and the pickup pipe is an absolute **** to sort. We have one up on eBay at the mo but to be honest I doubt I will be doing them apart from for my own engine builds in the future, Scott kindly lent me the bits and the cajoling to do one and I have done a couple for my own engines but they are incredibly expensive to make needing a cnc machined block for the pump takeoff due to space constraints !!
  8. Cheers folks, Andy - had a look at those on ebay.de, only confusion was the bore but I'm 99% sure that theyve got their listing wrong as KS only list a 96.5mm piston not a 97.5 (which would be pushing a CIH bore a bit far I'd think?) Will get my machine shop to find out if they can get the relevant KS part, pretty sure they can. H-400, it would be nice to put forged pistons in it but I'm pretty sure the budget won't stretch to it. Will check just in case! cheers Nat
  9. Just canvassing for opinion here, any thoughts on pistons for a 2.4 16v ( frontera block cut down senator head ) What are the best options before going to full forged aftermarket items
  10. Micsmanta that's not what they were referring to. Johnboy had made the point that it would be pretty simple to stick a single downdraft twin choke weber carb on the stock xe inlet, which it would !! Interesting thought for a road rally car to keep things simple!! Manta 1800 dizzy re curved and would be pretty good to be fair. Wouldn't make a lot of power but bags of torque and dirt cheap and simple to do on a carbed car
  11. It's almost certainly voltage regulator. Simple thing to remember is that if it gets into the red properly rather than pretending, it will start pushing water out of the rad cap. As was suggested, get an infra red thermometer from maplin etc as it's always useful to have anyway and you can check how hot it actually is
  12. not really to be honest. Its not really a sump baffle its a windage tray, it removes excess oil clinging to the crankshaft and stops it splashing back onto the crank. This was far more of a problem with the front drive sump than the manta sump. it's pretty difficult to get oil surge with a manta sump and correct oil level
  13. If the cam is already used and you have put some assembly lube between it and the followers it will all be fine.
  14. Thanks folks! Should be at billing fingers crossed!
